TicTacToe帮助重画功能

Question

我正在创建一个使用Java的TicTacToe游戏，我想要一些帮助。

玩家获胜后，我希望游戏要求复赛。发生这种情况，但按钮面板不刷新。我已经使用了“重绘”功能，但它似乎不起作用。 预先感谢您

下面是代码：

import javax.swing.*; 
import java.awt.*; 
import java.awt.event.*; 
import java.io.*; 
import java.util.*;

public class TicTacToeGUI extends JFrame implements ActionListener{ 

    JButton btn1; 
    JButton btn2; 
    JButton btn3; 
    JButton btn4; 
    JButton btn5; 
    JButton btn6; 
    JButton btn7; 
    JButton btn8; 
    JButton btn9; 
    public JFrame window = new JFrame("Tic Tac Toe"); 
    public int playerTurn = 0; 
    public boolean win = false; 
    String letter = ""; 
    private final String[] yesno = {" ", "Yes", "No"}; 

    public TicTacToeGUI(){ 
     window.setTitle("Tic Tac Toe"); 
     window.setSize(300,300); 
     Dimension dim = Toolkit.getDefaultToolkit().getScreenSize(); 
     window.setLocation(dim.width/2-window.getSize().width/2, dim.height/2-window.getSize().height/2); 
     window.setLayout(new GridLayout(3,3)); 

     this.addStuff(); 
     window.setDefaultCloseOperation(EXIT_ON_CLOSE); 
     window.setVisible(true); 
     window.setResizable(false); 

    } 

    public void addStuff(){ 

     btn1 = new JButton("");

Answer 1

您需要设置文本为空

setText(""); 

//伪代码

foreach(Button temp in windows.allChild) { 
    temp.setText(""); 
} 
windows.repaint();
